| Research Abstract |
The spacial and temporal distribution of enhanced cytokinin signal in flower bud was investigated to elucidate its effect on induction of decorative flower morphologies of torenia (Torenia fournieri Lind.). To induce wide and narrow paracorollas and serrated petal, it was shown thathigh cytokinin signal should be localized to the site of morphological change. Further, enlargement ofreceptacle, which was induced by enlargement of floral meristem by the localized high cytokinin signal,presumably promoted paracorolla initiation.
